Create a Dialog based application and add a menu. First you need to declare some variables in the the header file of your Dialog. Code: #define MYWM_NOTIFYICON (WM_USER+1) //User defined messages. CMenu m_TrayMenu; //Displaying menu when right clicked on the system tray. Should be inside the class definition NOTIFYICONDATA tnd; //Icon Data afx_msg LRESULT onTrayNotify(WPARAM, LPARAM); //Function to handle the user messages Now put the following code in the OnInitDialog function Code: CString sTip(_T("Hello System Tray")); tnd.cbSize = sizeof(NOTIFYICONDATA); tnd.hWnd = this->GetSafeHwnd();; tnd.uID = IDR_MAINFRAME; //ICON RESOURCE ID tnd.uFlags = NIF_MESSAGE|NIF_ICON; tnd.uCallbackMessage = MYWM_NOTIFYICON; tnd.uFlags = NIF_MESSAGE|NIF_ICON|NIF_TIP; tnd.hIcon = LoadIcon(AfxGetInstanceHandle(), MAKEINTRESOURCE (IDR_MAINFRAME)); //ICON RESOURCE ID lstrcpyn(tnd.szTip, (LPCTSTR)sTip, sizeof(tnd.szTip)); DWORD dwMessage = NIM_ADD; Shell_NotifyIcon(dwMessage, &tnd); m_TrayMenu.LoadMenu(IDR_MENU); //MENU RESOURCE ID. Add user-defined message handler Code: ON_MESSAGE(MYWM_NOTIFYICON,onTrayNotify) Now define the body of onTrayNotify as follows Code: LRESULT CWallpaperDlg::onTrayNotify(WPARAM wParam,LPARAM lParam) { UINT uMsg = (UINT) lParam; switch (uMsg ) { case WM_LBUTTONDBLCLK: this->ShowWindow(SW_SHOW); break; case WM_RBUTTONUP: CPoint pt; GetCursorPos(&pt); m_TrayMenu.GetSubMenu(0)->TrackPopupMenu(TPM_RIGHTALIGN|TPM_LEFTBUTTON|TPM_RIGHTBUTTON,pt.x,pt.y,this); break; } return TRUE; } Now if you want to add the functionality that whenever someone hits the cross it should be minimized to the system tray then add the WM_CLOSE event handler and remove the call to the CDialog::OnClose(); and add the following code. Code: ShowWindow(SW_HIDE); Now in the WM_DESTROY message of the dialog add the following lines to delete the icon from the system tray and clean up the tray. Code: Shell_NotifyIcon(NIM_DELETE,&tnd); The sample application has been done in VC++ 7.1 compiler and if you wish to transfer that and view them in older version 7.0 then you need to do the following
One more thing... Don't forget to define #define _WIN32_WINNT 0x0501 before including "windows.h" file.
Because some of the features of API functions and structures are defined for specific Windows versions or highers. For example : Code: //shellapi.h typedef struct _NOTIFYICONDATAA { DWORD cbSize; HWND hWnd; UINT uID; UINT uFlags; UINT uCallbackMessage; HICON hIcon; #if _WIN32_IE >= 0x0500 CHAR szTip[128]; DWORD dwState; DWORD dwStateMask; CHAR szInfo[256]; _ANONYMOUS_UNION union { UINT uTimeout; UINT uVersion; } DUMMYUNIONNAME; CHAR szInfoTitle[64]; DWORD dwInfoFlags; #else CHAR szTip[64]; #endif #if _WIN32_IE >= 0x600 GUID guidItem; #endif } NOTIFYICONDATAA,*PNOTIFYICONDATAA; As you see, as the constant _WIN32_IE has higher values, higher features are enabled. From MSDN : Code: Windows Server 2003 family _WIN32_WINNT>=0x0502 Windows XP _WIN32_WINNT>=0x0501 Windows 2000 _WIN32_WINNT>=0x0500 Windows NT 4.0 _WIN32_WINNT>=0x0400 Windows Me _WIN32_WINDOWS=0x0490 Windows 98 _WIN32_WINDOWS>=0x0410 Internet Explorer 6.0 _WIN32_IE>=0x0600 Internet Explorer 5.01, 5.5 _WIN32_IE>=0x0501 Internet Explorer 5.0, 5.0a, 5.0b _WIN32_IE>=0x0500 Internet Explorer 4.01 _WIN32_IE>=0x0401 Internet Explorer 4.0 _WIN32_IE>=0x0400 Internet Explorer 3.0, 3.01, 3.02 _WIN32_IE>=0x0300
Hi, i did this application in VC++6.0, but i want to display the balloon tool tips for my system tray icon, i know how to do this. when i'm working in version 6.0 its giving errors as error C2039: 'uTimeout' : is not a member of '_NOTIFYICONDATAA' error C2039: 'dwInfoFlags' : is not a member of '_NOTIFYICONDATAA' erro C2039: 'szInfo' : is not a member of '_NOTIFYICONDATAA' ..... .... but when i did the another application application for system tray icon in VC++.Net then it runs perfectly and the system tray icons shows the balloon tips. i know its due to the shellapi.h version with respective to the os. now my question is how can i made VC++6.0 use the latest version of shellapi.h and able to display the balloon tool tips in my application. please help me to solve this. Thanks in advance. -Gopinath
Can someone walk me though the part Add user-defined message handler I am still learning VC and im familiar with the MFC ClassWizard but where do I go from there?
You need to add the code in the Message Map. In Dialog based application you will find that in the Dialog cpp file. Find the MESSAGE_MAP there.
Thanks. Now its saying that it cant find m_TrayMenu I havent defined a Member Variable called m_TrayMenu is obviously why But I cant because there is no Menu Control IDs in the wizard. I did add a IDR_MENU1 by right clicking NEW MENU. Why is it not showing up under the MFC Class Wizard? Or am I doing it wrong? Thanks for the help...
Why don't you download the code and try running it. I see you should have the IDR_MENU and not IDR_MENU1 but I could not get what you meant by
I followed the instructions for the system icon, and my app is able to get one to show up...however the icon disappears as soon as the mouse hovers over it. So obviously the tooltip and the right-click menu cannot be activated. What am I possibly doing wrong? I followed the instructions almost verbatim. I'm using Windows XP pro and Visual Studio 2005 version 8. Thanks for any help.
Disabling the menu item would be same for Normal Menu or for Any Windows control. There is an API EnableWindow and I think that should do it for you
I have tried it, but it does not work, I debugged the code and I found that update handler is called before oncommand.
